Purple-marked rice male sterile lines developed in Guangxi
The rice male sterile lines carrying the purple-leaf marker trait, Xianhong A and Zhihong A, developed by the research team led by Guangxi Outstanding Expert Researcher Liang Shirong and Guangxi Academy of Agricultural Sciences Vice President Researcher Deng Guofu, passed the field technical appraisal organized by the office of the Guangxi Regional Crop Variety Approval Committee and conducted by a relevant expert group on August 3, 2007. After strict field investigation and indoor microscopic examination, and after hearing the research team's technical report and answers to questions, the expert group unanimously concluded that Xianhong A and Zhihong A have stable agronomic traits, stable male sterility, and good flowering

New upland rice variety developed in Shandong, agronomist Xu Defang successfully breeds it
In the golden autumn season, a new upland rice variety carefully cultivated over 3 years by Xu Defang, an agronomist at the Dongying Branch of the Shandong Academy of Agricultural Sciences, has achieved a bumper harvest. According to calculations, it yields more than double that of the current upland rice variety 297, with a yield of 600-650 kg per mu, marking a breakthrough in China's upland rice breeding. Xu Defang used more than 30 ancestral lines provided by Professor Li Zichao of China Agricultural University, discovered a dwarf-stalk mutant line from the tall-stalk line 33-1, and from it selected a group of 9 lines, namely early-maturing, glutinous, early

Virus-free Technology and Industrial Development of Superior Potato Varieties
Aiming at the main problems currently existing in potato production, this study seized the favorable opportunity of planting-structure adjustment and extensively introduced superior potato varieties from home and abroad. Through trials and market-demand surveys, "Luyin No. 1" was selected as the main cultivar for Qingdao, with Kexin No. 3, Kexin No. 4 and Huayuan 525 as companion cultivars. Through systematic research on virus-free technology, rapid propagation technology and the acclimatization and transplanting technology of virus-free test-tube plantlets, the optimal virus-free protocol for potato was determined: taking 0.1-0.2

Potato Harvester Successfully Developed, Mechanized Harvesting Realized
On July 17, at the provincial potato mechanized planting and harvesting on-site demonstration meeting held in Xiazhaizhai Village, Nianbo Town, Ledu County, Qinghai Province, it was observed that a single-operator potato harvester produced and developed by a provincial private enterprise completed the potato harvest of a 8-fen plot in less than 40 minutes, equivalent to a whole day's workload of 10 laborers, while the machine's selling price was less than 1500 yuan. The staff of the Qinghai Provincial Agricultural and Animal Husbandry Machinery Extension Station distributed and promoted 40 such potato harvesters with an operating efficiency of 1.2 mu per hour to 20 grassroots stations on site.

Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

What measures promote rice root development?
1. Sow early at the right time. When the temperature stabilizes at 5°C, begin sowing and raising seedlings; do not raise seedlings for the May crop. When the temperature stabilizes at 13°C, begin transplanting; do not transplant for the June crop. Transplant during the high-yield period to gain accumulated temperature, which is beneficial to root development. 2. Prepare the land carefully and create the conditions. Do a good job of plowing and rotary tilling; generally the plowing depth is 20 cm and the rotary tilling depth is 14 cm. Keep the plowing or rotary tilling depth uniform, so that the mud is not exposed even in water an inch deep, creating the conditions for root development. 3. Strengthen management and promote development. First, seedling-field management: control the temperature well, water reasonably, spray fertilizer on the leaves, and prevent
